Anti-corrosion structure and method of prestressed anchor cable anchorage device

Abstract

The invention discloses an anti-corrosion structure and method of a prestressed anchor cable anchorage device. The structure comprises a first thermoplastic pipe and a second thermoplastic pipe. The first thermoplastic pipe wraps an exposed anchorage device of a prestressed anchor cable and stretches to wrap an exposed anchor cable of the prestressed anchor cable to form a first stretching section, and a pipe orifice of the first stretching section is tightened through a binding wire. The second thermoplastic pipe wraps the first stretching section and the exposed anchor cable, the outer end of the second thermoplastic pipe stretches outwards to form a second stretching section, the second stretching section is folded backwards, a pipe orifice of the second stretching section is tightenedthrough a binding wire, and the end of the exposed anchor cable is wrapped. According to the method for protecting the exposed anchorage device and the exposed anchor cable of the prestressed anchor cable, corrosion caused by solarization, rainwater and other adverse factors of the exposed anchorage device and the exposed anchor cable can be effectively avoided, and the design strength of the prestressed anchor cable is guaranteed. The anti-corrosion structure and method are especially suitable for the situation that the exposed time of a foundation pit is long, and the prestressed anchor cable needs to be tensioned additionally.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an anti-corrosion structure and anti-corrosion method of a prestressed anchor cable anchorage. Background technique [0002] In foundation pit support construction, the actual anti-corrosion treatment of anchor cables and anchors is often not enough to ensure long-term anti-corrosion of exposed parts. Therefore, attention should be paid to adopting anti-corrosion measures to achieve long-term anti-corrosion requirements for the exposed ends of prestressed anchor cables. Contents of the invention [0003] The invention mainly aims at the deficiencies of the prior art, and provides an anti-corrosion structure and anti-corrosion method of a prestressed anchor cable anchorage. The method is simple, easy to operate, and low in cost, and can effectively solve the problem that the exposed end of the prestressed anchor cable is easily corroded. [0004] For realizing a...
